This is one of the most awe-inspiring sites I’ve visited to date, because of the feeling of great age and meaning that surrounds this site – more so than most other sites I have been to. The volcanic tuff making up the boulders in this vicinity is relatively soft ( for rock! ) but also quite rough to the touch. Yet, at this site, a lot of the surface area is worn smooth and patinated. That is the kind of look only rock touched by human hands over a great period of time will acquire.
Some researchers speculated about the astronomical ties this site might have to the winter solstice, and estimated that the site may have first come into use at around 250 B.C. to 250 A.D. If true, that is an impressive age.
